[2. the feature summary of electronic data conversion equipment]
Then, the feature summary of Fig. 2 to Fig. 4 to the electronic data conversion equipment 1 of present embodiment is used to be described.
Fig. 2 is the figure of an example of the show image of the picture show image of the electronic data that present embodiment is shown and the frame image data of formation dynamic image data.In addition, the figure of Fig. 3 (a) to be the figure of the setting example of the brightness value of the pixel of the picture show image that electronic data is shown, Fig. 3 (b) be setting example of the brightness value of the pixel that each frame image data is shown.In addition, Fig. 4 is the figure of other setting examples of the brightness value of the pixel that each frame image data is shown.
Electronic data conversion equipment 1 electronic data to be named converts dynamic image data to.About the kind of the electronic data as converting objects, as long as can show on picture, then without particular limitation of.Such as, as the electronic data becoming converting objects, there are electronic document, view data, Web page (specifically, forming the html document, view data, electronic document, text data etc. of Web page) etc.In addition, an example of the picture show image of the electronic data shown in Fig. 2 is the picture show image of certain colored still image.
In electronic data conversion equipment 1, specifically, when people watches the picture of the computer display being shown dynamic image by the reproduction processes of dynamic image data, generate the dynamic image data that with the naked eye can identify the image identical with the picture show image of electronic data.And, in electronic data conversion equipment 1, even if carry out the behavior such as screenshotss or picture photography when showing dynamic image data (hereinafter referred to as " picture replication ".), also generate the dynamic image data that correctly can not copy the picture show image of electronic data.
In more detail, as shown in Figure 2, generate from the static image data that the picture show image with electronic data is suitable the dynamic image data be made up of multiple frame image data.Each frame image data is static image data, by making dynamic image data reproduce, multiple frame image datas of formation dynamic image data being presented on picture successively with regulation frame per second, and repeatedly showing.As the form of this dynamic image data, such as, also can apply Adobe Flash(trade mark) SWF(Small Web Format).But the form of dynamic image data is not limited to specific form.
Forming each frame image data of dynamic image data is the static image data that the color of each pixel changes to the color different from the color of the pixel of the same coordinate of the original static image data of the picture show image being equivalent to electronic data respectively.Specifically, the color of pixel is red as the three primary colors of light, i.e. R(), G(is green), B(is blue) combination (example of the value of pixel of the present invention) of respective brightness value shows.Therefore, in the picture show image and frame image data of electronic data, between each pixel that coordinate is identical, set the brightness value of each frame image data in the mode that the brightness value of the primary colors of at least 1 in R, G, B is mutually different.
In addition, when the brightness value of any primary colors making the arbitrary coordinate of the picture show image of electronic data is L, in the frame image data of frame number i, making with the brightness value of the same primary color of the picture show image same coordinate of electronic data is l
itime, l
ibe set to meet following formula (1).
[several 1]
Above-mentioned various in, FN is the frame number of dynamic image data.Frame number is the number of the frame image data forming dynamic image data.As the formula (1), between FN frame image data, the brightness value of the pixel that the arithmetic average of the brightness value of the pixel that coordinate is consistent with each other is consistent with coordinate in the picture show image of electronic data is consistent.
The setting example of the brightness value of each frame image data when Fig. 3 illustrates that frame number is 3.In addition, the example of Fig. 3 is example when making that the minimum value of brightness value is 0, the maximum of brightness value is 255, and brightness value is larger, and expression is more bright color.Fig. 3 (a) illustrates the brightness value of 9 pixels R, G, B separately of certain coordinate of the picture show image of electronic data.In addition, Fig. 3 (b) illustrates and be positioned at the brightness value with R, G, the B of the pixel in the pixel same coordinate of brightness value shown in Fig. 3 (a) in each frame image data.As shown in Figure 3, in the picture show image of electronic data, between the coordinate of the combination identical (that is, homochromy) mutually of the brightness value of R, G, B, even if in frame image data, be also set to the combination of mutually identical brightness value.That is, in the picture show image of electronic data, between the coordinate that the combination of brightness value is mutually identical, the set model for the brightness value of each frame image data is also identical.Such as, as shown in Fig. 3 (a), because the combination of the brightness value of the pixel of right-hand member one row is identical, therefore as shown in Figure 3 (b), even if in each frame image data, the combination of the brightness value of the pixel that right-hand member one arranges is also identical.Due to brightness value as above can be set, therefore such as also can use and answer with each Color pair on the picture show image of electronic data and represent the conversion table of the brightness value set model separately for R, G, B of each frame image data, by systems control division 20, each frame image data be set to the brightness value of R, G, B.This conversion table also can be stored in advance in storage part 15, also can be made by systems control division 20 when dynamic image data generates.In addition, such as systems control division 20 also can use corresponding with each brightness on the picture show image of electronic data and represent the conversion table of the set model of the brightness value for each frame image data.If now, then table size can be reduced.
When reproducing the dynamic image data be made up of frame image data as above, certain is presented at instantaneously, and picture forms any one frame image data of dynamic image data.Therefore, even if replicated the show image of the picture of certain moment by picture replication, the color of each pixel of the image copied, also different from the color being positioned at the pixel of same coordinate on the picture show image of original electronic data respectively.Thus, the picture show image of electronic data can not correctly be copied.On the other hand, by showing each frame image data being formed dynamic image data successively with specific time interval, the people of viewing picture recognizes to show and carried out average color to the color represented by the combination of the brightness value of R, G, B of the pixel of each two field picture in each coordinate.Thereby, it is possible to make the people that have viewed picture be identified as to show the picture show image of original electronic data.
But when including the brightest white and the darkest black in the picture show image at electronic data, all brightness values of R, G, B of this pixel are the values that the minimum value of scope desirable with brightness value is identical, or the value identical with maximum.So, even if for each frame image data, as brightness value, also must set minimum value or maximum respectively, the part that the color of all frame image datas is identical with the color of the picture show image of original electronic data can be produced.
Therefore, systems control division 20, before delta frame view data, also can carry out the gray compression conversion of the picture show image of electronic data.Gray compression conversion refers to the minimum value of amplitude, i.e. brightness value and the difference of maximum that reduce gray scale, reduces contrast.Specifically, the brightness value when making that the minimum value of brightness value is 0, the maximum of brightness value is Lmax, before the compressing and converting of arbitrary primary colors be L1, compressing and converting after brightness value when being L2, calculate L2 by following formula (2) or formula (3).
[several 2]
When L1 < Lmax/2
[several 3]
When L1 > Lmax/2
In above-mentioned formula, K to be value be more than 1 constant.Through type (2) or formula (3), brightness value is close to Lmax/2.Further, be the brightness value of 0 before switching, become K after conversion, be the brightness value of Lmax before switching, become Lmax-K after conversion.And, between L2 and the minimum value of brightness value and between L2 and the maximum of brightness value, even if due to the minimum surplus also producing K respectively, therefore, it is possible to make the color of each frame image data different from the color of the picture show image of original electronic data.In addition, in gray compression conversion, the algorithm beyond formula described above (2) and the algorithm shown in formula (3) can also be used.In addition, also can change not make the minimum value of brightness value, and other brightness value carries out compressing and converting close to the mode of minimum value.In addition, also can change not make the maximum of brightness value, and other brightness value carries out compressing and converting close to the mode of maximum.
In addition, as shown in the example of Fig. 3 (b), in the picture show image of electronic data, between the coordinate that the combination of brightness value is mutually identical, when also setting the combination of mutually identical brightness value in frame image data, sometimes such as easy from 1 frame image data identification word or pattern etc.Therefore, such as shown in Figure 4, the set model of R, G, B brightness value separately for each frame image data also can be determined randomly to each coordinate.That is, the set model of the brightness value of each coordinate also can become irregular set model.Thereby, it is possible to change the set model of brightness value to each coordinate, multiple pixels of mutual same color on the picture show image of electronic data can be made, frame image data becomes mutually different colors.
Then, the frame per second of the dynamic image data that generate and the defining method of frame number are described.About frame per second and frame number, also can be set by user respectively, also automatically can be determined by electronic data conversion equipment 1, or, also can be stored in storage part 15 as fixed value predetermined value.
When frame per second determined by electronic data conversion equipment 1, such as, the refresh rate (vertical synchronizing frequency) of estimated computer display is first obtained by systems control division 20.About this refresh rate, such as, also can be inputted by user.Or, when to be reproduced for the purpose of dynamic image data by electronic data conversion equipment 1, also can be obtained the setting of the current refresh rate of display part 12 by systems control division 20.Further, systems control division 20 determines frame per second according to acquired refresh rate.Specifically, the value of frame per second is made to become below the same value of refresh rate.Further, such as, any one value in the value of frame per second and the approximate number of refresh rate can be made identical.Thereby, it is possible to suppress the flicker of the image when reproducing dynamic image data.But when frame per second is too low, when reproducing dynamic image data, the people that sometimes have viewed picture is difficult to the picture show image identifying original electronic data.Therefore, the lower limit that can be defined as frame per second can also be set.Now, systems control division 20 take frame per second as the mode determination frame per second of more than lower limit.Such as, be 60Hz at refresh rate, when the lower limit of frame per second is 24fps, frame per second becomes 30fps or 60fps.
When frame number determined by electronic data conversion equipment 1, such as, systems control division 20 is determined according to frame per second.Owing to passing through all frame image datas of display, people can recognize the color identical with the color of each pixel of the picture show image of original electronic data, therefore when passing through to increase frame number, show all time needed for frame image data elongated time, be sometimes difficult to the picture show image identifying original electronic data.Therefore, the higher limit of all frame image data required times of display is such as preset.Further, systems control division 20 take the required time when showing all frame image datas successively with determined frame per second as the mode determination frame number of below set higher limit.Now, more improve frame per second, more can increase frame number.
When being determined frame per second and frame number by user, such as also can by reproducing the dynamic image data generated, enable electronic data conversion equipment 1 have user while confirm the dynamic image shown by display part 12, adjust the function of frame per second and frame number respectively.
[3. the action of electronic data conversion equipment]
Then, the action of Fig. 5 to electronic data conversion equipment 1 is used to be described.
Fig. 5 is the flow chart of the processing example of the systems control division 20 of the electronic data conversion equipment 1 that present embodiment is shown.In addition, the flow chart shown in Fig. 5 is the flow chart of the process illustrated when determining for the brightness value of each frame image data set model randomly to each coordinate.
First, systems control division 20 obtains electronic data as acquisition unit, acquired electronic data is converted to static image data (step S1).Specifically, systems control division 20 as electronic data acquisition unit, such as, is obtained and is operated operating portion 11 by user and the electronic data of specifying.Now, systems control division 20 also such as can obtain electronic data by Department of Communication Force 13 and network from other information processors, also can read in electronic data from disk DK by drive division 14, also can obtain the electronic data be stored in storage part 15.Further, systems control division 20 such as generates static image data by the rasterisation carrying out acquired electronic data as converting unit, and the data file as prescribed form is stored in storage part 15.As the form of static image data, such as, there are jpeg format, tiff format, BMP form etc.In addition, systems control division 20 obtains pixel count in length and breadth and the total pixel number of generated static image data.In addition, systems control division 20 when as static image data, can omit the process carrying out changing at acquired electronic data.
Then, the bitmap image of generated static image data carries out launching (step S2) by systems control division 20 on the regulation region of RAM19.This bitmap image is such as corresponding with each coordinate and set the data of the array structure of each brightness value of R, G, B.The picture show image of this bitmap image and electronic data is suitable.In addition, systems control division 20, when converting electronic data to static image data, is not that static image data is first saved as data file, but directly can sets static image data on RAM19 as bitmap image yet.
Then, systems control division 20 generates multiple frame image data as static image data generation unit in step S3 ~ S16.
First, systems control division 20 determines the frame per second (step S3) of the dynamic image data that will generate according to the refresh rate of estimated computer display as frame per second determining unit.Then, systems control division 20 according to determined frame per second, determines the frame number FN(step S4 of the dynamic image data that will generate as synthetic image number determining unit).In addition, about the example of the defining method of frame per second and frame number, owing to being illustrated, explanation herein is therefore omitted.
Then, systems control division 20 carries out gray compression conversion (step S5).Specifically, systems control division 20, by R, G, B brightness value separately of each pixel of launched bitmap image, is updated to described formula (2) or formula (3), calculates the brightness value after conversion.Further, systems control division 20 brightness value of the brightness value calculated to bitmap image is rewritten.
Then, systems control division 20 be assigned to the setting regions of the bitmap image of frame image data on FN RAM19 memory space in (step S6).
Then, systems control division 20 sets 0(step S7 on the variable y representing Y-coordinate), the variable x representing X-coordinate sets 0(step S8).
Then, systems control division 20, from the original bitmap image launched in step s 2, obtains the brightness value (step S9) of R, G, B of the pixel of coordinate (x, y).Then, systems control division 20, to each R, G, B, to meet the mode of above-mentioned formula (1), drives the brightness value (step S10) set each frame image data randomly.Then, fixed brightness value is set as the brightness value (step S11) of the coordinate (x, y) of each setting regions by systems control division 20 respectively.
Then, systems control division 20 adds 1(step S12 on variable x), decision variable x whether little than the value of the pixel count of the transverse direction obtained in step sl (step S13).Now, systems control division 20, when variable x is less than the value of horizontal pixel count (step S13: yes), transfers to step S9.
On the other hand, systems control division 20, when variable x is more than the value of horizontal pixel count (step S13: no), variable y adds 1(step S14).Then, whether systems control division 20 decision variable y is than the value little (step S15) of the vertical pixel count obtained in step sl.Now, systems control division 20, when variable y is less than the value of longitudinal pixel count (step S15: yes), transfers to step S8.
On the other hand, systems control division 20 is when variable y is more than the value of longitudinal pixel count (step S15: no), by the bitmap image set in each setting regions, respectively as the file of the frame image data of prescribed form, be stored into (step S16) in storage part 15.
Then, systems control division 20 generates dynamic image data (step S19) as dynamic image data generation unit.Specifically, systems control division 20 combines each frame image data of the frame 1 ~ frame FN generated, and generates dynamic image data.Now, the frame per second setting section of systems control division 20 such as in dynamic image data sets fixed frame per second.In addition, in the combination of above-mentioned each frame image data, also using above-mentioned frame number as benchmark, such as, can combine regularly in the mode of ascending order or descending, or also can the mode that described frame number combines randomly as benchmark is not formed.When generating dynamic image data thus, systems control division 20 makes the process shown in Fig. 5 terminate.
The dynamic image data generated, can be reproduced by the information processor that can reproduce the data of this form.By being reproduced the dynamic image data generated by information processor as above, be included in the frame image data in dynamic image data, such as, according to frame 1, frame 2, frame 3 ... mode described combination order and be presented at successively on picture with the frame per second set in dynamic image data.Further, after showing last frame image data, initial frame image data is again shown.
As described above, according to the present embodiment, systems control division 20 will represent that the static image data of picture show image of electronic data obtains as bitmap image, value, the i.e. brightness value of the pixel at least partially of the static image data that the change generating determined number of frames obtains and the frame image data that obtains.Now, systems control division 20 makes the arithmetic average of the brightness value of the pixel that coordinate is consistent with each other between each frame image data equal with the brightness value of the pixel of the picture show image of original electronic data.Further, systems control division 20 generates the dynamic image data showing the frame image data generated with determined frame per second.
Therefore, even if replicated the picture show image of certain moment by picture replication, the picture show image copied also only changes 1 frame image data of the color of pixel at least partially picture show image with the picture show image from original electronic data is identical.On the other hand, due on each coordinate, the people that have viewed picture recognizes the color represented by combination of the arithmetic average of each brightness value of R, G, B of the pixel of each frame image data, therefore, it is possible to identify the picture show image of original electronic data.Thereby, it is possible to prevent the content be presented on picture from correctly being copied.
In addition, because systems control division 20 obtains electronic data, obtain static image data by carrying out conversion to acquired electronic data, therefore, it is possible to more correctly identify the content of the picture show image of the electronic data that can be presented on picture.
In addition, systems control division 20 also can by determining the set model of the brightness value for each frame image data randomly to each pixel, improve the possibility making color is mutually identical on the picture show image of original electronic data multiple pixels become mutually different colors on frame image data.Now, can make to become difficulty from the content of the original picture show image of copied picture show image identification.
In addition, systems control division 20 also can carry out the conversion that the minimum value of brightness value of the pixel of the picture show image of original electronic data and the difference of maximum are reduced, and makes the arithmetic average of the brightness value of the pixel that coordinate is consistent with each other between each frame image data equal with the brightness value after conversion.Now, can prevent the content be presented on picture from correctly being copied further.
In addition, systems control division 20 also can determine the frame per second of dynamic image data, and determines the frame number of dynamic image data according to determined frame per second.Now, the frame number of applicable frame per second can be determined, thereby, it is possible to easily identify that the mode of picture show image adjusts with the people that have viewed picture.
In addition, in the above-described embodiment, although for all pixels of frame image data, become the color that the color of the pixel consistent from coordinate in original electronic data is different, but also for the pixel of a part, the color that the color of the pixel consistent with coordinate in original electronic data is identical can be become.
In addition, in the above-described embodiment, although change the set model of the brightness value for each frame image data to each coordinate, i.e. every 1 pixel, also the large unit of area ratio 1 pixel can be shown to change the set model of brightness value with picture.Such as, the picture show image of original electronic data is divided into multiple region, makes the set model of brightness value mutually different between zones.Specifically, such as systems control division 20 makes above-mentioned conversion table to each region.Now, systems control division 20 to make each conversion table for the mode that the set model of the brightness value of same color or same brightness value is mutually different between each region in original electronic data.Further, systems control division 20 carries out the conversion table of reference to each area change, while to each frame image data setting brightness value.In addition, as long as between at least 2 regions in multiple region, make the set model of brightness value mutually different.
In addition, in the above-described embodiment, the arithmetic average of the brightness value of the pixel of each frame image data is completely equal with the brightness value of the pixel of the picture show image of original electrical image data.But, as long as viewing to the people of the picture that generated dynamic image data reproduces to identifying that the picture show image of original electrical image data does not have in the scope of obstacle, or, if the eyes of employment the different scope of identification colors can not be carried out, on the brightness value of the pixel of the arithmetic average of the brightness value of the pixel of each frame image data and the picture show image of original electrical image data, then there are some deviations also can (about such as, ± 10).Also the scope of this deviation can be preset.In addition, now, even without carrying out gray compression conversion, the color of the pixel of each frame image data also can be made different from the color of the pixel of the picture show image of original electronic data.But, even now also can gray compression conversion be carried out.Changed by this gray compression, what can expand between the color of the pixel of each frame image data and the color of the pixel of the picture show image of original electronic data further is different.
In addition, in the above-described embodiment, although the three primary colors that the color of pixel is combined light show, such as, the combination of four primaries can also be used.
In addition, the frame image data of the color of the picture show image by the original electronic data of shake performance can also be generated.Now, when using Neutral colour etc. in the picture show image at original electronic data, frame image data combines the color of multiple pixel to show the color of the picture show image of electronic data.Now, when watching with 1 pixel unit, the difference of the brightness value of the pixel that the arithmetic average due to the brightness value of the pixel consistent with each other of coordinate between each frame image data is consistent with coordinate in the picture show image of electronic data does not drop in prescribed limit.That is, when only observing 1 pixel, the average color of each frame image data is different from the color of the picture show image of electronic data sometimes.But, in the prescribed limit be made up of multiple pixel (such as, the scope of respectively 9 pixels of 3 pixels in length and breadth) on when observing, as long as make the color recognized when people watches the picture shown by the reproduction of dynamic image data, seem identical with the color of the picture show image of electronic data.Now, as long as such as make the difference of the brightness value of the pixel of the arithmetic average of the brightness value of multiple pixels of the prescribed limit the being arranged in each frame image data scope consistent with the picture show image coordinate being located at electronic data be in prescribed limit.
